Managing Bioabsorbable Vascular Scaffold Failure: Combined Scaffold Restenosis and Late-Acquired Coronary Aneurysm Treated With Self-Expandable Stent

Published:December 19, 2014DOI:https://doi.org/10.1016/j.cjca.2014.12.021

      Abstract

      A 50-year-old man underwent coronary angiography for stable angina with evidence of chronic total occlusion of the right coronary artery. Chronic total occlusion recanalization was performed with implantation of 4 overlapping bioresorbable vascular scaffolds. At 12 months, elective follow-up coronary angiography documented an asymptomatic 90% in-scaffold restenosis of the right coronary artery located in the mid portion of a newly late-acquired aneurysm. To address the challenging issue introduced by the varying reference vessel diameters, a self-expandable stent was implanted.

      Résumé

      Un homme de 50 ans a subi une coronarographie pour une angine stable montrant une occlusion totale chronique de l’artère coronaire droite. La recanalisation de l’occlusion totale chronique a été réalisée au moyen de l’implantation de 4 endoprothèses vasculaires biorésorbables qui se chevauchent. À 12 mois, la coronarographie de suivi a démontré une resténose intrastent de 90 % asymptomatique de l’artère coronaire droite située dans la partie moyenne d’un anévrisme acquis récemment. Pour régler le problème complexe que représentent les différents diamètres vasculaires de référence, une endoprothèse auto-extensible a été implantée.
